The brooder trays 46 are slidably arranged in the bottom of the tray compartment 14 and in alignment with the lower portion of the heater. In this way it will be seen that the brooder compartment is exposed to the heat and upon the rotation of the fan, the air is heated and circulated throughout the casing. In other words, the air movement is stimulated by the fan and flows through the tubular frame in a circulatory movement in a continuous stream, thoroughly Warming the contents of the racks at a temperature adjusted by means of the thermostat.

When the air is overheated the thermostat automatically switches off the heater and the electric light which is extinguished, and When the air is cooler the thermostat automatically switches on the heater and the electric bulb. During the process the motor is continually operated so that the circulation of the air is continuous and in that Way there is no dead 8E0; or air pocket throughout the Whole of t e casin What 1. In an incubator, a stationary casing having a brood chamber and a rack chamber, a tubular rack frame having open front and rear ends and a casing closing in the sides of the tubular rack frame the latter being rockably supported in said casing, a heater and fan secured to the inside of one of the end walls in the stationary casing facing one of the open ends of said rack frame for stimulating the flow of air through said stationary casing and ensuring a circulatory movement through the rack frame and around the sides thereof.

2. In an incubator, a stationary casing having doors leading into a brood chamber and a rack chamber, a tubularrack frame having open front and rear ends and a casing closing in the sides thereof said rack frame being rockably supported in said stationary casing with its front open end facing the doors in the stationary casing and the rockably supporting means being pivoted to the front and rear walls of said casing, a heater and fan stimulating the flow of air throughout said casing around the closed walls of said rack frame and throughthe open ends thereof and ensuring a circulatory movement through the rack frame and around the sides thereof.
